Timer class and javax.......
Hi,
Downloaded the latest java version to d:\download folder. The downloaded file has the name
" j2re-1.4.2_03-wndows-i586-p.exe ". The file size was about 14.53MB. Double clicking the same installed j2re1.4.2_03 in "C:\Program Files\java\j2re1.4.2_03" folder.
When I tried to compile Reminder.java program that comes with online Tutorial
from within C:\Program Files\java\j2re1.4.2_03 at MS-DOS prompt, I got the error message �class java.util.Timer not found in import�.
I also have Jdk1.1.3 in C:\jdk1.1.3 folder. When I tried to compile Reminder.java from within C:\jdk1.1.3 at MS-DOS prompt, got the same error message,
Even after changing path variable to C:\jdk1.1.3\bin. Please help.
Trying to compile any swing program at both DOS prompts gives error message �javax.__________ not found in import�. Can�t figure out why. Please help.

j2re1.4 is a runtime only (ie j2re = Java Runtime Engine) It will not compile java files.
The timer class was introduced with Java version 1.3.
You currently have a very old version of 1.1.3.
You need to download the j2se1.4.2 SDK - http://java.sun.com/j2se/1.4.2/download.html
The size is closer to 50MB :-)
Cheers,

Combining LVOOP DVR with Asynchronous Dynamic Dispatch and Preserve Run-Time Class
OK, the title sounds like a cornucopia of LVOOP terms. But there's a reason. This is in a way an extension of THIS thread.
What I'm doing recently is creating a LVOOP approach to loading Completely Asynchronous UI elements into subpanels. This I have combined with a global repository for the objects (which are essentially singletons with a UI functionality) which are shared via DVR, thus eliminating a lot of synchronisation headaches).
This means that I can ahve a universal framework for launching the UI elements into a subpanel. The changes made on the Object there are automatically reflected in the global repository.
So far so good.
What I don't like too much is a combination of two seemingly awkward code constructs I need in order to keep things running.
Weird construct 1:
I have defined a "Launch UI" function in my parent class which is Dynamic Dispatch (Allowing each object to take care of launching its own UI). This takes a parent object DVR as a second input which I make sure is of the exact same type as the object type being invoked by using the code shown below. The ACTUAL Type of both inputs to the launch VI within the IPE are identical. This is guaranteed because I require each new class to override this function.
Here I pass the DVR from outside the IPE to the "Launch" VI but the Object obtained within the IPE retains information required for DD thus ensuring that the VI called for launching the UI is identical to the ACTUAL object type in the DVR. This works OK and by placing this weird construct WITHIN the parent class, abuse is minimised, it works fine and seems to have no major side-effects.
So now we have a VI running asynchronously in the background which belongs to a specific object but has a DVR which it *thinks* is of a Parent Type but, because of the steps taken earlier, is actually of the same type as the object itself.
In order to make use of the functionality defined in this actual object type, I need to continuously re-interpret the Object within the IPE as shown below. Otherwise only the Parent functionality is available.
If I am accessing only methods of the parent class, then the Preserve functionality is not needed.
Is there a more elegant way to do this? I find the net result of this code and type-juggling to be really useful and much easier to manage than the non-DVR route since the synchronisation issues disappear. By making the IPE usage near-atomic we remove the chances of deadlock.
All editing done in the UI of the asynchronous VI is reflected automatically in any subsequent usage of the DVR. Even if the DVRs are not shared between VIs, this makes (for me) the headache of synchronisation easier. If you start expanding this beyond the limits of a single VI, the benefits in Synchronisation become really huge. You can even have multiple UI objects operating on the same data in the background without extra synchronisation needs. The only synchronisation required is a global "Data updated" for the object in question whereby the UI elements simply update their indicators and controls from the DVR again. This is trivial.
Thus I am convinced that the net result of this is very beneficial.
My question is if there's a better, safer or more "official" way to do this?
I was about to start a new Idea for combining the "Preserve Run time Class" and the DVR Terminal of the IPE so that the casting is done automatically. We could then have a double input to the IPE, the DVR (of base type) plus the ACTUAL Type of the object but of course returning an error if the types are incompatible. It would be like an "Imposter" DVR input for the IPE which allows a re-interpretation of the object type.
Would all of this go away if we allowed Dynamic Dispatch to work with DVRs? Probably.

Say hello to my little friend.
RFC 2323 FHE-Compliant
Solved!
Go to Solution.You guys rock!
I didn't even think of casting the DVR like that. Kinds stupid of me but I never would have thought it would work. Cool.
Also, Yeah, the limitation of no IPE in the Launch VI was one I spotted quite early on. this is why my Launch VI also doesn't accept more data than is absolutely neccessara because a DVR access in that VI will of course cause a lockup. I have the system so far now that I can have a SINGLE Launch VI (Which is NOT overridden, so the limitation refers to only a single VI now which is certainly better.
So again guys, thanks for helping out an old newbie. I've been around for quite a while, have made many posts but I love the way I just keep learning from others in the Forum. This is just why I absolutely LOVE it here.

Timer Class not accurate and slows down my animation!?
Does anyknow how why my timer object is not accurate and why it slows down my animation that is also present on my GUI at the same time?
I have a timer in the form of 0.00 the left of the decimal point should represent a second but it doesnt, run my code and see for yourselves. below is my code if anyone can fix these 2 problems i will be very thankfull:

xfoI'm (being lazy and) using the older RT app posted on your last thread. I removed the
TimeNow timer from the RT class and used System.currentTimeMillis (as you requested) to
determine the elapsed time during the animation (see "startTest", "stop" and
"movingObject" methods). Also changed the DecimalFormat to NumberFormat and set the
"maximumFractionDigits" to "2" so it will truncate the fraction to two digits (more simple
than before). Made arrangements for the ShapeMovingPanel class to update the
"timerJTextField" during the animation (RT.updateTime method).
The MouseMotionListener is causing the animation to appear jerky and uneven. The
"mouseMoved" method is very busy while the mouse is moving. You might consider recording
the "mousePressed" events instead of the "mouseMoved" events, ie, the events where the user
is attempting to click inside the moving shape. It would allow the app to be more
responsive and might eliminate the uneven motion of the animating shape.

Need help with my alarm clock, with Timer task and Timer classes
k everything is almost complete to get this alarm to work. It goes off and everything. But the thing is that it has a start button and when you click it to start the alarm the text changes to "Stop". This way if the user wants he can turn it off. Yet it works fine, the only problem is when the alarm actually goes off, the button text doesnt change back to "Start".

can someone tell me how many seconds the cross fade is when running your Ipod 6th Gen nano in that mode? I teach spin class and want to know how much time I'm losing in that mode.
You aren't losing any time in that mode, but I believe it is a 10 second fade out/fade in.

Time constraint classes and screen number for absence type
Hi all,
What should be the Time constraint classes and screen number for absence type.
The different absence types are annual leave, sick leave , study leave , personal leave, maternity leave , juryduty leave nad leave without pay etc
Kindly help.
Regards,The time constaint class depends on the client requirement.
eg.if they want that a error needs to be generated while overlapping absences or warning message is required.
Time contraints comprise the following:
Time constraint classes that determine which collisions in time data records are allowed
Time constraint table that contains the time-based collisions allowed in the time data records
Time constraint indicator that displays whether a new data record that collides with an existing time data record can be transferred to the system or whether the transfer is prohibited
For screen number you will have to see if the is quota based deduction or just an absence. Here is the documentation of screen number from SAP
In the standard system, the following numbers are allocated to the screens:
1. 2000 - General absence
This screen is used for all absences which do not require special processing (such as paid leave of absence for getting married).
2. 2001 - Quota deduction
This screen is used for entering data on leave or time in lieu of overtime.
3. 2002 - Work incapacity
Use this screen for all absence types where continued pay should be taken into account automatically by the system.
4. Special screens have been developed for the following absence types:
2003 - maternity protection, parental leave
2004 - military and non-military service
2005 - work incapacity (Netherlands)
Please go through the documentation of the configuration.

Design console and javax.naming.directory.basicattributes class
Hi all,
Is it possible to do the following in the design console?
BasicAttributes basicattributes = new BasicAttributes(true);
basicattributes.put(new BasicAttribute(contextName, "Weblink"));
basicattributes.put(new BasicAttribute(contextCode, "Web001"));
your help would be much appreciated..While Kodo cannot persist those elements out of the box, you can easily
use the externalization framework to persist the data in a format your
database and Kodo can understand.

Loading classes and performance
In most of the cases, when a program requires more than 3 classes from a package, we often write the code as import package.* (e.g. when we need lots of GUI components we often need to import javax.swing.*). But in that package, for example the javax.swing package, it seems that most of the classes from that package are not needed. My question is, If we import each class we need individually, will it improve the performance? Or is it a bad programming style? (import each class individually often needs more than 8 lines of codes or even more!)
Thanks in advance. DavidsonWell...when you design your code you will have a very good idea of what classes and what packages you will need to use when you actually write your programs. When you write your program, if you specifically know that you will be using just two classes of a particular package then there is absolutely no point at all in you including statements importing the entire package. But you have to be careful.
That is the reason why a programmer should spend a lot of time in the design rather than jumping into coding. When you have your design on paper in all details, you will know your program as a whole thoroughly. Then you will get a chance to think about optimization techniques for your code. Of course, including an entire package does no harm to your program but...unless you would be using a lot of classes in a package, be specific because this will improve your final code documentation...any documentation explaining your code for that matter. Besides, there is always a difference between a practise that is OK and a good practise :-)

SetBackground and basic class and method calling stuff
A few days ago I posted a thread about some paint problems. I was then told I was a bad programmer :P So I've read up a little on the subject. Hope this code looks better then the last (event though it's not as "complete" as the last one was).
Now I've got a few new problems though.
// Java Document
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Diamonds2 extends JFrame{
public static void main(String[] args) {
JFrame f = new JFrame("Diamonds 2");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
Container panel = new DiamondsPanel();
f.getContentPane().add(panel, BorderLayout.CENTER);
Container statusPanel = new DiamondsStatusPanel();
f.getContentPane().add(statusPanel, BorderLayout.PAGE_END);
f.setBackground(Color.black);
f.pack();
f.setResizable(false);
f.setVisible(true);
Game d2 = new Game();
d2.game();
class DiamondsPanel extends JPanel {
public static int BallRadius = 16;
public static int posx = 100;
public static int posy = 1;
public DiamondsPanel() {
super();
setOpaque(false); // we don't paint all our bits
setLayout(new BorderLayout());
setBorder(BorderFactory.createLineBorder(Color.black));
public Dimension getPreferredSize() {
Dimension panelSize = new Dimension(800, 580);
return panelSize;
protected void paintComponent(Graphics g) {
super.paintComponent(g);
Dimension size = getSize();
// set color
g.setColor (Color.red);
// paint a filled colored circle
g.fillOval (posx, posy, BallRadius, BallRadius);
public void updateGamePanel() {
posy--;
repaint();
class DiamondsStatusPanel extends JPanel {
public DiamondsStatusPanel() {
super();
setOpaque(false);
setLayout(new FlowLayout());
setBorder(BorderFactory.createLineBorder(Color.black));
public Dimension getPreferredSize() {
Dimension panelSize = new Dimension(800, 20);
return panelSize;
protected void paintComponent(Graphics g) {
super.paintComponent(g);
class Game {
public void game() {
while(0 < 10) {
try {
Thread.sleep(10);
} catch (InterruptedException e) {}
// System.out.println("Something is happening");
}I can't set the background. I've tried to apply setBackground color to the constructors of each of the panel classes too but that won't work either.
Secondly. How should I do the animation (the red circle should move) now. I knew how to do it before but with this new structure (I found in some swing tutorial) I can't figure it out. I've tried intializing a thread in the class Game since it couldn't be done (according to the compiler) in main. Also, before I could use isVisible() to run the while-loop now that didn't work either and I suppose using 0 < 10 is not a very good way to do it. I also made an update method in the DiamondsPanel class but I don't know how to call it. I understand I'm not doing this as it should be done. I also can't find any place that makes me understand how to do it :P
Any answers will be welcomed with open arms (except mean ones xD).
Thanks alotStyrisen wrote:
I got the background to work.. really don't know what I did. It works thoughGreat
So should the code for animating the ball be inside the DiamondsPanel class? Or where should it be?This is one of the crucial questions when developing an OOP app: what objects to create and what code goes where? I have not done animations, but I believe that there is a 2D forum here in the Sun forums. You might consider asking this over there (but if you do, please be sure to have each thread reference the other so as to avoid duplication of effort from the volunteers who help).
How should the code look like? Should I use runnable? You're definitely going to need to use separate threads. That much I'm sure of.
Should I make an infint loop? No.
Should I use a timer class? Probably.
Is it a bad idea to divide the panels into classes?Not only is it not a bad idea, it may be a good one.
Good luck!

hi!
ne idea why we have two timer classes that is one in util and another in swing package.any diff in the twoLess than a minute of actually looking at the API documentation reveals that (surprise!) they are not the same. Not only that, the documentation of one of them says this:
"In v 1.3, another Timer class was added to the Java platform: java.util.Timer. Both it and javax.swing.Timer provide the same basic functionality, but java.util.Timer is more general and has more features. The javax.swing.Timer has two features that can make it a little easier to use with GUIs. First, its event handling metaphor is familiar to GUI programmers and can make dealing with the event-dispatching thread a bit simpler. Second, its automatic thread sharing means that you don't have to take special steps to avoid spawning too many threads."Instead, your timer uses the same thread used to make cursors blink, tool tips appear, and so on." -
Hello,
I'm using a javax.management.timer.Timer MBean and registering it with the local MBean server. Instead of adding notifications programmatically, I want to be able to do it from Jconsole.
However, from Jconsole I can invoke any Timer operation (like removeNotification, etc.) except for all 4 addNotification operations, as they are all disabled.
Is this not supported? Why are they disabled? Is there a way to enable these operations?
I'm new to JMX and would appreciate any help.
Thanks!Hi Eamonn,
Thanks for the example! I have a follow-up question though:
The example you gave uses a StandardMBean. Our application already has a DynamicMBean. Is it a good practice for dynamic beans to extend the timer class. Or should it only be done with standard mbeans?
Also I've noticed that the listener that I registered and our DynamicMBean run in the same thread, so when the listener is running, the bean gets blocked and I cannot invoke any other operation. I found your blog about listeners and tried the following example but it doesn't help. How do I resolve this big issue?
class myListener implements NotificationListener {
private final Executor executor =
Executors.newSingleThreadExecutor();
public void handleNotification(Notification n, Object handback) {
executor.execute(new Runnable() {
public void run() {
blockingOperation();
My dynamic mbean looks like this:
public class MyDynamicBean extends Timer implements DynamicMBean {
myListener listener = new myListener();
MBeanServer mbServer;
public void register() {
mbServer = MBeanServerFactory.newMBeanServer();
ObjectName beanName = new ObjectName("MyDynamicBean");
mbServer.registerMBean(this, beanName);
super.start();
mbServer.addNotificationListener(beanName, listener, null, null);
protected Integer addNotification(String type, String message, long deltaMillis) {
if (not registered)
register();
long dateMillis = System.currentTimeMillis() + deltaMillis;
Date date = new Date(dateMillis);
return super.addNotification(type, message, null, date);
public void unregister() {
if (registered) {
ObjectName beanName = new ObjectName("MyDynamicBean");
super.removeAllNotifications();
m_mbServer.removeNotificationListener(beanName, m_listener);
super.stop();
mbServer.unregisterMBean(beanName);
Any help is highly appreciated!

Document Classes and other Questions
Basically, i am working on an application that will eventually be deployed to the desktop as an AIR application.
I am wanting to create an Analogue clock and Digital clock with a button that toggles the display between either one when pressed. As well as this, i will be wanting to display the Date below, i am having a number of issues however.
I have the code sorted for three of the four components, i have not attempted to figure out the button thus far as i would be more than happy to have the digital clock, analogue clock and date all being displayed on a drag and drop desktop application first. When i say i have it sorted, i have a fully working analogue clock which i have managed to display on the desktop through air on its lonesome, however, i did not include the drag and drop function. For the digital clock and date components i am not sure how to configure them into document classes. The main issue i am having is i do not know if you can reference a dynamic text box within a movie clip to a document class.
This is the code to show the date
[code]{
var currentTime:Date = new Date();
var month:Array = new Array("January","February","March","April","May","June","July","August","September","Octo ber","November","December");
var dayOfWeek:Array = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
date_text.text = dayOfWeek[currentTime.getDay()] + " " + currentTime.getDate() + " " + month[currentTime.getMonth()] + " " + currentTime.getFullYear();
[/code]
I have put the actionscript frame inside the movie clip file, and i have given both the movie clip, and the dynamic text box within the movie clip the instance name "date_text".
Basically, i am just struggling in how to put this code into a working document class, since the digital clock and date functions are both, some what similar, i feel the solution to one will more than likely lead to me discovering the solution for the other.
The other problem i am having, i do not know how i will display all of the components on one air application. I am assuming, that you create one other document class file which links the other four together? i have tried to do this by just linking a new FLA file with the analogue clock, but it does not work. The code for that is below.
[code]package
import flash.events.Event;
import flash.display.MovieClip;
public class time1 extends MovieClip
public var now:Date;
public function time1()
// Update screen every frame
addEventListener(Event.ENTER_FRAME,enterFrameHandler);
// Event Handling:
function enterFrameHandler(event:Event):void
now = new Date();
// Rotate clock hands
hourHand_mc.rotation = now.getHours()*30+(now.getMinutes()/2);
minuteHand_mc.rotation = now.getMinutes()*6+(now.getSeconds()/10);
secondHand_mc.rotation = now.getSeconds()*6;
[/code]
That is the original clock document class (3 Movie clips for the moving hands, and the clock face is a graphic, which i may have to reference somehow below)?
[code]package
import flash.display.MovieClip;
public class main extends MovieClip
public var hourHand_mc:time1;
public var minuteHand_mc:time1;
public var secondHand_mc:time1;
public function main()
hourHand_mc = new SecondHand();
addChild(mySecondHand);
hourHand_mc.x = 75;
hourHand_mc.y = 75;
minuteHand_mc = new SecondHand();
addChild(mySecondHand);
minuteHand_mc.x = 75;
minuteHand_mc.y = 75;
secondHand_mc = new SecondHand();
addChild(mySecondHand);
secondHand.x = 75;
secondHand.y = 75;
}[/code]
This is my attempt at creating the main document class in a seperate FLA file to attempt to load the analogue clock, and later on the Digital Clock, Date Function and Toggle Display button in the same AIR application.
Any help on this is much appreciated, i have been reading up a lot on it through tutorials and the like, but i can't seem to fully grasp it.why do you have code in a movieclip?
if you want to follow best practice and use a document class you should remove almost all code from timelines. the only timeline code that might be reasonably used would be a stop() on the first frame of multiframe movieclips.
so, you should have a document class. that could contain all your code but it would be better to just have your document class create your 2 clocks and date objects and possibly manage toggling between the two clocks. you could have a separate class the tracks the time and date and that class is used by your two clock classes and your date class. -
My web page uses a Java Applet to allow my visitors to replay chess games; the Chess Viewer Deluxe applet was written by Nikolai Pilafov some time ago and has been working properly for some time (until recently). I don't monitor this part of my site regularly so I am not sure when it began to fail. On his web site [http://chesstuff.blogspot.com/2008/11/chess-viewer-deluxe.html] he has a link to check LiveConnect object functionality (which fails for OBJECT tags). His recommendation is to "seek platform specific support which might be available from the JRE developers for your platform".
I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Until I checked the LiveConnect object functionality, I was unable to identify the source of the console error messages. This does seem to be the smoking gun.
Is Apple aware of this problem? Are these classes no longer supported? Has anyone else had this problem? You can attempt to recreate the problem locally by going to my web page: http://donsmallidge.com/DonSmallidgeChess.html
Thanks in advance for any help you can provide!

Middle Name: null
Last Name: null
Phone Number: null
Address: null
getBirthDay: null
null
i don't know why it's all null. i assign something in the default constructor. it shouldn't be "null".
does anyone know why?when you create 2 class using netbean editor, person.java and test.java
i never compile person.java.
when i finish typing these 2 class and i just right click test.java and run.
my question is do i need to compile person.java before i run test.java directly??
does Netbean compile it automatically when i run test.java first time?
i add another constructor Person constuctor with one parameter in Person.java and create 2nd object to test the 2nd constuctor and run.
All the codes work, so does the first default constructor. i don't why is that.
Then i removed what i added and restore back to where it didn't work before and test again. it works.
@_@. so weird.
problem solved. thank you
